With huge wings and a body to match, this adult roc is a formidable predator. Claws large enough to carry a human prove useful in battle, and this giant bird has little trouble bearing you on its back. Most of the day it hunts, returning to The Keep to rest and spend time with the other creatures. Silva Forest and some of the mountains are the hunting grounds for the large birds, and it's a good thing that they can manage on their own; they eat a tremendous amount of food. Adult rocs help feed the younger ones, and teach them how to hunt. Like most magical creatures, only one egg comes from a breeding, so each youngling is important. The largest trees around The Keep cradle massive nests, and rocs are very protective of their nesting areas. The only animals not intimidated by the size of these creatures are the gryphons, who enjoying wheeling in the sky with them, and occasionally hunting together.

Enormous birds of prey, wild rocs will sometimes carry off a sheep from a village's flock. This usually only happens if food is scarce; their hunting grounds reach from Silva Forest to the high mountains. Rocs are known to be very dangerous by common folk, but if trained, they can have very calm temperaments. If attacked or startled, however, they do pose a significant threat. Their senses can easily be heightened, and rocs are too large for any human to control. Powerful enough to carry their magi through the skies, rocs make lethal companions, though they are becoming increasingly difficult to find. They hide their eggs high in the mountains, and explorers do not dare to venture near their nesting grounds often. Rocs are fiercely protective of their nests, and will attack anyone who approaches their enormous eggs.
